Var. apuana Issel. PL 1, fig. 12. This variety has some 

 analogy with P. hordeiim, but differs by the shape of the aper- 

 ture. The shell is more slender than that of the type, of a 

 brown color, and has the right margin of the aperture more 

 regularly arcuate. Punta del Sagro in the Apuan Alps (Pupa 

 avenacea var. apuana Issel, Dei Molluschi race, nella Prov. di 

 Pisa, in Mem. Soc. Ital. di Sci. Naturali, ii, no. 1, 1866, p. 21. 

 Del Prete, Bull. Soc. Malac. Ital., v, p. 81, pi. 1, f. 10-12). 



According to Del Prete, it is found in abundance at Carrara 

 above Torano, at Tarnbura, and rare at Matanna. One of his 

 figures is copied, pi. 1, fig. 12. His natural-size figure is 6.3 

 mm. long. The name appeared as Alloglossa avenacea var. 

 apuna Issel, in Westerlund, Malak. Bl., vol. 22, p. 130. 



Form elatior Paulucci. Larger, both in length and width, 

 but differing chiefly by being much more slender. Avellana in 

 Umbria and at Caramanico (Pupa avenacea form elatior Paul., 

 Bull. Soc. Malac. Ital., vii, 1881, p. 119).
